New product allows you to explore record-setting extreme weather

We've launched a new extreme weather product this week: Record Extremes. Recent, globally record-setting years have demanded a product that combines U.S. and international record extremes into one, easy to use interface. The Record Extremes page will give you the option to see U.S. and international records on a map and table. You can select any combination of record types at once, which, combined with the map, provides a interesting visual way to investigate record-setting events. The product uses data from three sources: (1) NOAA's National Climate Data Center, (2) Wunderground's U.S. records, and (3) Wunderground's International records.

The NCDC records begin in 1850 and include official NOAA record extreme events for ASOS and COOP weather stations in all 50 U.S. states as well as Puerto Rico, the Virgin Islands, and the Pacific Islands. In this database you can find records for maximum high temps, minimum high temps, maximum low temps, minimum high temps, snow, and precipitation on daily, monthly, and all-time scales.

The Wunderground extremes were compiled by our weather historian Christopher C. Burt. Chris monitors 300 stations across the U.S. for Record Extremes in maximum and minimum temperature, precipitation, and snow events. Most of these U.S. records go back to the end of the 19th century, though the oldest site in this database is Charleston, SC, where precipitation records started in 1737! Internationally, Chris monitors 150 countries worldwide for all-time record high temperatures and all-time record low temperatures. If you're interested in diving deeper into extreme weather in the U.S. and abroad, Chris's book Extreme Weather is an excellent resource.

Figure 1. All-time snow records broken during the Groundhog Day Blizzard of 2011. These records were found by selecting NCDC as the source, a start date of 2011-01-31, an end date of 2011-02-02, "maximum snowfall," and "all-time."

We built the Record Extremes product to make it easy to find specific records you're looking for, or just browse the records in general.

Check records that were set on a specific dateYou can check on records that were set yesterday, for example, by setting the calendar to yesterday's date, and selecting all the record variables and types that you're interested in.

Explore all records set in a certain time range2011 was a record-setting year for the U.S., and most of the records were high maximum temp and high minimum temps. To see all of these warm records that were set last year, select "NCDC" as the source, 2011-01-01 as the start date and 2011-12-31 as the end date. Select Maximum High Temp and Maximum Low Temp in weather variables, and select all-time in the record type.

View current standing international records in the Wunderground databaseSelect either the Wunderground International records, and instead of choosing a date range, select "Show current standing records." This will bring up all standing records in the database for whatever record variable and type you select. Whereas we've collected every record ever set or broken from NCDC, the Wunderground records are always the current, standing record, whenever it was set. As you move your map around the globe, you'll see each country's all-time maximum high temp and all-time maximum low temp.

A tornado watch has been issued for the entire viewing area until 8:00 Friday evening. A line of strong storms is expected to roll across southeastern North Carolina throughout the afternoon and evening hours.

The primary threat will be from damaging winds in the line of strong storms, but an isolated tornado could be possible.

Quoting Chapelhill: The line of deep convection across SC,GA, and AL is limiting deeper mositure transport and higher dewpoints from advecting into NC and VA. We are also seeing a lot of high cloud blow off that is limiting some of the heating. No one out of the wood, but these are good signs.

Quoting TropicalAnalystwx13:Not necessarily, the temperature here continues to rise despite the cloud cover. If we got any more moisture, I would seriously be freaking out right now, because these are spring-like values.

Nothing good coming out of this yet...

MCD #156 posted at comment 567 speaks to exactly what you two were discussing...

TORNADOES WILL BE POSSIBLE...PARTICULARLY IN ASSOCIATIONWITH ANY LEWP PATTERNS AND CONVECTION WELL IN ADVANCE OF THE FRONTWHERE SFC WINDS ARE SOMEWHAT MORE BACKED RELATIVE TO THE WLY FLOWALOFT. UNCERTAINTY IN THE NRN EXTENT OF THE UNSTABLE SECTOREXISTS...AS WELL AS THE IMPACT OF MID/HIGH CLOUDS OVER CNTRL/ERN NCAND NERN SC. HOWEVER...IN BOTH INSTANCES...INSTABILITY IS EXPECTEDTO BE SUFFICIENT...GIVEN THE MAGNITUDE OF FORCING FOR ASCENT... SUCHTHAT A SVR/TORNADO THREAT WILL LIKELY EVOLVE.

Only the Sky knows what will be this afternoon and eve. My guess for now, watch for a thin line of trouble from Southcentral NC N-eastward toward the Virginia border.

EFFECTIVE THIS FRIDAY AFTERNOON AND EVENING FROM 120 PM UNTIL 800 PM EST.

TORNADOES...HAIL TO 1 INCH IN DIAMETER...THUNDERSTORM WIND GUSTS TO 75 MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE AREAS.

THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 95 STATUTE MILES EAST AND WEST OF A LINE FROM 5 MILES NORTH NORTHWEST OF PATUXENT RIVER MARYLAND TO 25 MILES SOUTHWEST OF MYRTLE BEACH SOUTH CAROLINA. FOR A COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH OUTLINE UPDATE (WOUS64 KWNS WOU8).

REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR TORNADOES AND SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS AND POSSIBLE WARNINGS.

OTHER WATCH INFORMATION...CONTINUE...WW 35...WW 36...WW 37...

DISCUSSION...INTENSE BOW ECHO SYSTEM IS MOVING RAPIDLY ENEWD ACROSS CENTRAL SD AND THIS WILL CONTINUE INTO NORTHEAST SC AND SOUTHEAST NC DURING THE NEXT SEVERAL HOURS. FARTHER NORTH...STORMS ARE EXPECTED TO CONTINUE TO DEVELOP AND INTENSIFY ALONG/AHEAD OF THE RAPIDLY MOVING COLD FRONT. WARM SECTOR ENVIRONMENT HAS WARMED SUBSTANTIALLY WITH SURFACE TEMPERATURES IN THE 70S TO LOW 80S...AND WITH DEW POINTS IN THE 50S...SUFFICIENT INSTABILITY AND VERY STRONG LOW- AND DEEP-LAYER SHEAR WILL SUPPORT POTENTIAL FOR SEVERE STORMS INCLUDING A FEW SUPERCELLS. PRIMARY THREATS ARE EXPECTED TO BE DAMAGING WIND GUSTS AND A FEW TORNADOES.

AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL SURFACE AND ALOFT TO 1 INCH. EXTREME TURBULENCE AND SURFACE WIND GUSTS TO 65 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO 450. MEAN STORM MOTION VECTOR 24050.
